What are the main causes of varicose veins?

Varicose veins are usually caused by weakness in the walls and valves of the veins. Inside the veins are small one-way valves that open to let blood through and then close to prevent it from flowing backwards. Sometimes the walls of the veins stretch and lose their elasticity, causing the valves to weaken. Weak or damaged valves can cause varicose veins.

Arteries carry blood from the heart to the rest of the body. The veins return blood from the rest of the body to the heart. For blood to return to the heart, the veins in the legs must work against gravity. There are many factors that can cause varicose veins.

The most common are pregnancy, standing for long periods of time, and obesity.
